The paper describes the first implementation of phase angle measurements in an industrial state estimator.Transducers for measuring phase angles using satellite clock synchronization were installed at Sevillana de Electricidad and incorporated into the data acquisition subsystem of the EMS. The State Estimator was modified to support the processing of phasor telemetry. The enhancements to the state estimator algorithm are described in the paper. The modified state estimator was subjected to intensive testing prior to installation in the field. The results of all experiments as well as classification of phasor measurement effectiveness are reported in the paper. Phasor measurements were found to provide valuable information about the power network and improve the accuracy of the state estimation.
